%% Here is some Postscript for setting the gamma values using table lookup
%%
%% These tables don't do anything currently.  Its a straight 1-1 mapping.
%%
%% But maybe somebody will figure out some tables if I provide the template :-)
%%
%% This is for fooling around with color correction.  None of the
%% values in this file are tuned for the 2300 DL yet.  So far, I
%% have not come across a *process* for determining what should go
%% into this file.
%%
%% This defines a set of four PS procedures, one for each of C, M, Y, and K,
%% whose input is a value in the range 0.0..1.0, and whose output should be
%% a corrected value in the same range.
